Application "med June 16,

This invention relates to new and useful improvements in signals, and particularly to direction signals for automobiles.

One object of the invention is to provide a device of this character wherein a single operating means-is capable of moving a signal member or arm 'intoandout of signaling position to indicate one or the other of'two directions. I I Another object is to provide a device of this character wherein the operating-means for the signal arm is adapted to be turned, to a certain degree, in each direction to accomplish the raising and lowering: of the arm, and further rotation in either direction to cause the arm to rotate simultaneously with its swinging movement.

Other-objects and advantages will be apparent from the following description when taken in. connection with the accompanying drawings.

In the drawings: v

Figure 8 is a transverse section, on the line 88 of Figure 1.

Referring particularly to the accompanying drawings. 10 represents an elongated casing which is provided with the means 11 for attaching same to the front of an auto mobile, at the drivers side, so that said casing will project horizontally from the side of the automobile. On the outer end of the casing 10 there is formed a cylindrical casing 10, having the front and rear brackets 12 in which is rotatably supported the shaft 13. Disposed horizontally through the inner end portion of the casing 10 is a shaft 14:, which projects rearwardly toward the driver, and is provided with a handle 15 by means of which the shaft may be rotated. Fixed on this shaft, within the 'and 33.

rod 17, said rod extending longitudinally of the casing and being pivotally connected to a second arm 18, associated with the shaft 13'. =Extending vertically from the lower 'wallz'of the casing 10, adjacent the inner end thereof, is an apertured bracket 19, while a 7 similar bracket 20 depends from the upper wall, adjacent the outer end of the casing. Rotatably supported in these brackets 19 and 20, and extending longitudinally within the casing, is a rockshaft 21-. Onthe-outer end of'the rockshaft 21is-fixed a radial arm 22. which is pivotally connected with a slidable plate 22 carried by the front bracket 12, said plate. being provided with a pro- 'je cting stop block 23, to which'reference Wlll be madelater herein. Fixed on the rock shaft-21, adjacent its innerend, is a bifurcated arm 24 which straddles the. beforementioned 'rod 17, and is adapted to be moved from "side to side, to cause the said Shaft/to rock, asth d the two bevelgears 32 and 33, loosely mounted on the shaft 13. On theend of the shaft 30, remote from the gear131. is a radial arm 34. which has its outer end-secured to the endplate 35', of the signal casing 36. This plate 35 has a central opening 37 through before-mentioned bolt 29 is secured in the other end plate-35 of the signal casing 36. and clamps the"glass side plates 38' said plate and the plate 35. Formed integrally casing, is a radially extending arm 16, to which 1s pivotallyiconnected .one end of a which the hub 26 is loosely disposed. The

for engagement with the before-mentioned stop block 23. It will be notedthat the gear 31 is in constant mesh with the gears 32 Assuming the signal casing to be in vertical posltion, so that the glass panels contaming the legend Right are directed forwardly and rearwardly, respectively, the driver grasps the handle 15 and rotates the shaft 14 toward the right, which exerts a pull on the rod 17 and causes the rocking of the yoke, and the downward swinging movement of the signal casing into horizontal extended position, at the side of the automobile, within full view of drivers approaching from the front or from the rear. A rotation of the shaft 14 toward the left swings the casing back into its vertical, nonsignaling position. Upon continued rota tion of the shaft 14 toward the left the rod 17 swings the bifurcated arm 24 whereby to rock the shaft 21, to slide the plate 22 downwardly until the stop block 23 is in the path of the lug of the gear The gear 33 is thus held against rotation, and upon further turning of the shaft 1 1, in the direction above mentioned, the rod 17 swings the signal arm toward lowered signaling position, whereby the gear 31 will roll around on the gear 33, with the result that the signal arm is rotated to display the legend Left to view, from both the front and rear of the auto-. mobile. Turning the shaft 1 1 to the right swings the signal arm into vertical position again, without rotation by the gears, as said gears 32 and 33 are loose on the shaft 13. Then, upon further turning the shaft 14:, toward the right, the rod 17 will rock the shaft 21 to shift the plate 22' upwardly to dispose the stop block in the path of the end of the gear 32, with the result that the gear 31 will roll on thisgear 32, as the shaft 14 is turned to swing the signal arm downwardly, so that said signal arm will be rotated to display the legend Right.

By this construction, the operator can swing the signal member from vertical to horizontal position, and back again, without rotation of the signal member, or he can cause the rotation of said member, in either direction, by simply continuing the rotation of the shaft 14 in the direction corresponding to the legend to be displayed.

hat is claimed is:

1. A signaling device comprising a signal arm capable of swinging in a vertical plane and axial rotative movements, and an operating means connected with the signal arm and movable in one direction to simultaneously rotate the arm, and to swing the arm from vertical to horizontal position, and movable in the other direction to swing the arm into avertical position.

2. A signaling device comprising a signal arm capable of swinging movement in a vertical plane and axial rotative movement, and a rotatable operating means the movement of which in one direction produces a rotative movement of the signal arm, simultaneously with a swinging movement of said signal arm from vertical to horizontal position, and movement of the operating means in the opposite direction produces a swinging movement of the arm from horizontal to vertical position. i

3. A signaling device comprising a signal arm capable of swinging movement in a vertical plane and axial rotative movement, and a rotatable operating means connected with the signal arm, said operating means being adapted to be moved in one direction to produce a rotative movement of the arm simultaneously with a swinging movement,

of the arm from vertical position to horizontal position, and to be moved in the opposite direction to produce a swinging movement of the arm from horizontal position to vertical position.

1. A signaling device comprising a signal arm capable of swinging movement in a vertical plane and axial rotatable movement, and means operatively connected with the arm and operable in one direction to swing the arm from vertical position, to horizontal position, and to rotate the arm during such swinging movement, said operative means being adapted to be then operated in the opposite direction to restore the arm to vertidirection whereby to restore the arm to normal position without actuation of the selecting means. a

6. A signaling device comprising an axis, gears loosely mounted on the axis and each having a projection, a signal arm including a shaft having a gear in simultaneous engagement with said loose gears, a block selectively movable into the paths of said projections whereby to hold the engaged gear against rotation, an operating shaft, a link connected with the shaft and with the signal arm, and means connected with the said block and movable by the said link whereby to selectively dispose the block in the paths of said gear projections.

In testimony whereof, I affix signature.
